Creating a Web Font for Unicode Supplementary Multilingual Plane Symbols
Problem:
Using Unicode characters for playing cards in a web application reveals that some operating systems (e.g., Windows, Android) lack a font that can display these characters, specifically those within the Unicode Supplementary Multilingual Plane (SMP).
Solution:
Creating a Custom Font with Icomoon App:
- Select Your Symbols: Import the Unicode symbols you need (e.g., U 1F0A0 to U 1F0DF) into the Icomoon App.
- Create a Font File: Generate a font file that contains only the relevant code points. You can specify the characters' Unicode hex values.
- Export the Font: Save the font in a desired format (e.g., .eot, .woff, .ttf, .svg).
Using the Custom Font:
HTML:
- Include the @font-face Declaration: Include code to load the font from your server and set its properties.
- Use the Custom Font Class: Create a class (e.g., ".icon") that specifies the font.
- Add Icon Characters: Insert the Unicode characters you want to display within HTML tags using this class (e.g., ♣).
CSS:
- Define Icon Styles: Use CSS to set the appearance of icons (e.g., font-size, color).
- Optimize for Compatibility: Include multiple font file formats to ensure support across different browsers.
- Fallback Fonts: Specify fallback fonts in case the custom font is not available.
Benefits of Using Method 7:
Method 7, using the 'content' style rule and ':before selector', offers certain benefits:
- Simplified Code: It eliminates the need to copy-paste specific characters or use entity codes.
- Cross-Browser Support: Most modern browsers support the ':before' selector.
- Multiple Icons within a Single Tag: Unlike other methods, this method allows multiple icons to be displayed within a single HTML tag.
Considerations:
- IE6-7 and Certain Webkit Versions: These platforms don't support ':before' or UNICODE escape sequences.
- HTML Code Complexity: While this method simplifies code readability for icons, it increases complexity for the HTML structure.
